Rigid body ignores box colliders

So we have a box collider set up it's outside of the model but as you can see it wraps perfectly around it. but for some reason rigid bodies all ignore it, I tried looking up why but can't get an answer as to why that applies.
pretty much all objects simply fall through the floor.

any help appreciated.
i mainly just want my model to be able to toss it around.

 

Colliders interact with other colliders. You need to add one to the object you wish to collide with.

 

I can't see a box collider on you amazon box,may be that's the problem.

 

both do in fact have box colliders I even directly applied them to test. but both are ignored

now it apparently will just violently shake until it's off any other colliders.

 

have you tried setting a material to both of the colliders?

 

Are you applying forces to the box or is it just the default gravity?

 

default

 

what do materials do?

 

They set certain parameters of a collider, like its 'bounciness' and friction upon its surface. There should be a default one already included in unity, and creating your own isn't too difficult either.

 

that helped though it turns out there was a mesh collider applied to a wall that stretched across the room. so everything was inside of that causing it to freak out.
